BACKGROUND OF THE INVENTION

This invention relates generally to an accessory to a mobile computing device and, more particularly, to an apparatus that may be removably coupled to a bottom edge of a smart phone and configured for supporting the pinky finger of a person holding the case of the smart phone.

Smart phones have evolved to include very advanced technology, including cameras, large capacity batteries, large screens, and video capabilities. In reality, smart phones are like carrying a full laptop computer in a user's hand and can be heavy and awkward. Computers, however, have always been heavy and have often been carried in bags with handles or even with over-the-shoulder straps. Therefore, the weight of an electronic device is not new. The problem, now, is that many of the functions provided by a smart phone are accessed by a user pushing an icon or alphanumeric representation of a letter that appears on the screen of the mobile computing device, e.g., smart phone. Put simply, smart phones use touch screen technology as the primary input source. Users frequently hold the smart phone in one hand—grasped on the side edges by a thumb and fingers and supported by the pinky finger of that hand, and then the user pushes the touch screen letters to form a text message. Following this same procedure dozens or even hundreds of times a day often results in actual medical damage to the user's pinky finger—sometimes becoming so severe as to require medical attention as is now apparent in the news literature.

In another aspect, handheld computing devices frequently experience a completely dead battery at the absolutely worst times. For instance, a cell phone may have a battery that is badly in need of recharging at just the time the user needs to send an important text or receive an important call but the user is simply not in place to plug it in to receive a charge. Various devices, of course, are known in the art for charging a battery of a smart phone such a recharging unit with a USB connector that may be connected to the cell phone and configured to transfer an electrical charge from an AC outlet to the phone's battery or from an auxiliary battery to the phone's battery. Although presumably effective, recharging may not be possible while other accessories are plugged in to the mobile computing device.

Therefore, it would be desirable to have a finger support apparatus that plugs into a battery port or headphone jack port frequently found on the bottom edge of a smart phone case, the finger support apparatus being configured to support a pinky finger of a smart phone user. Further, it would be desirable to have a finger support apparatus that includes an electricity storage medium that may store a small amount of battery power and to impart that stored power to the cell phone when the finger support apparatus is plugged therein.

SUMMARY OF THE INVENTION

A finger support apparatus according to the present invention for use with a handheld computing device, such as a smart phone, includes a mounting portion having an inlet plug configured for insertion into the accessory port of the handheld computing device, the mounting portion having a fixed configuration that defines a longitudinal axis extending longitudinally away from the handheld computing device. The finger support apparatus includes a body portion coupled to the mounting portion and extending away from the lower frame portion, said body portion being configured to rotate axially about said longitudinal axis. The body portion may include a proximal edge adjacent said mounting portion, a distal edge opposite said proximal edge, and a pair of laterally opposed side edges extending between said proximal and distal edges. The finger support apparatus may include a keychain configured to mount to the finger support apparatus for storage and transport.

In another aspect, an auxiliary battery may be positioned in an interior space of the body portion and electrically connected to the inlet plug of the mounting portion of the finger support apparatus. Accordingly, electrical power from the auxiliary battery is transferred to the battery power source of the computing device via the input plug when the finger support apparatus is mounted thereto. In addition, the finger support apparatus may include an intermediate charging cap having electrical storage media therein and a charging port by which the charging cap may electrically connect to a charging cable to be charged or recharged. Then, the charging cap may be electrically connected to the finger support apparatus, whereby to provide the charge of electricity to the auxiliary battery and, indirectly to the battery of the mobile computing device.

A general object of this invention is to provide a finger support apparatus for supporting the pinky finger of a user of a handheld mobile computing device during one-handed use.

Another object of this invention is to provide a finger support apparatus, as aforesaid, that plugs into a port in a bottom edge of the computing device and which rotates to an orientation as desired by a user.

Still another object of this invention is to provide a finger support apparatus, as aforesaid, having an auxiliary battery that is itself rechargeable and configured to transfer stored electrical current to a battery of the computing device when the finger support apparatus is plugged into the mounting port of the computing device.

Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

A finger support apparatus according to the present invention will be described with reference to FIGS. 1A to 8 of the accompanying drawings. The finger support apparatus 10 may include a mounting portion 20 configured to plug-in or otherwise be inserted into a port 14 along a bottom edge of a case of a mobile computing device 12, such as a cell phone or smart phone of a type that is usually held by a single hand of a user. More particularly, the mounting portion 20 may include a plug 22 having a configuration complementary to that of the port of the mobile device, e.g., in the form of a USB, mini-USB, headphone jack, rechargeable battery jack, RCA connection, or the like.

The finger support apparatus 10 includes a body portion 30 rotatably coupled to the mounting portion 20 so that the orientation thereof may be adjusted by a user. It is understood that this rotational functionality (which may be referred to as a rotational swivel) may be accomplished by the body portion 30 having a rod, nub, or plug 31 extending from a proximal edge thereof and the mounting portion 20 defining a bore configured to receive the nub or rod therein (not shown). The body portion 30 may have a curved shape like the trigger of a firearm or, alternatively, have more of a square, round, or teardrop shape. Preferably, a top face of the body portion 30 may have a tactile surface 32, whether defining a groove or having a coarse, rubbery, or sticky surface operable to frictionally receive, nest, and hold a finger surface of a user. At least the top face or, in some embodiments the entire body portion 30, may exhibit a curved or slightly concave configuration so as to better receive a user's finger thereon. Multiple variations, showing the variations described above, are included in this application but all have substantially the same functionality.

Now, with greater detail, the body portion 30 may include a proximal edge 34 rotatably coupled to the mounting portion 20 and a distal edge 36 opposite the proximal edge 34, the distal edge 36 being displaced from and positioned outwardly away from the mounting portion 20. A pair of laterally opposed side edge 38 extends between the proximal edge 34 and distal edge 36, respectively. Together, these edges define the variations in the possible configurations shown in the drawings. Primed numerals will be used to clarify otherwise similar components.

For instance, in an embodiment shown in FIGS. 1a to 1d , the proximal edge 34 a of the body portion 30 has a straight line or linear configuration defining a first length. Further, the distal edge 36 a also has a linear configuration and is parallel to the proximal edge 34 a, the distal edge 36 a defining a second length that is shorter than the first length of the proximal edge 34 a. As such, the lateral side edges 38 a slope inwardly and toward one another as they extend from the proximal edge 34 a toward the distal edge 36 a. In other words, the body portion 30 may have a generally trapezoidal shape configuration with the proximal edge being the longer edge and the distal edge being the shorter edge.

In a variation, shown in FIGS. 2a to 2b , the proximal edge 34 b and distal edge 36 b have linear configurations and having an equal length. Similarly, the pair of lateral side edges 38 b having linear configuration and also define an equal length such that the body portion 30 has a generally square configuration.

In another variation, shown in FIGS. 3a to 3b , the proximal edge 34 c of the body portion 30 has a straight line or linear configuration defining a first length. Further, the distal edge 36 c also has a linear configuration and is parallel to the proximal edge 34 c, the distal edge 36 c defining a second length that is longer than the first length of the proximal edge 34 c. As shown, however, the proximal and distal edges in this configuration may be slightly rounded or curved. Further, each side edge 38 c has a curvilinear configuration (i.e., curved and not straight). As such, the lateral side edges 38 c slope in a gentle curve toward one another as they extend from the distal edge 36 c toward the proximal edge 34 c. In other words, the body portion 30 may have a generally trapezoidal shape configuration with the distal edge being the longer edge and the proximal edge being the shorter edge.

In still another variation, the body portion 30 has a generally circular configuration as shown in FIGS. 4a to 4b . In other words, the proximal, distal, and side edges are together arranged such that a peripheral edge of the body portion 30 has a circular shape configuration.

In another aspect, the present invention may include a keychain 40 specifically configured to receive and hold the finger support apparatus 10 when not otherwise coupled to the smart phone (FIGS. 5a and 5b ). More particularly, the keychain 40 may include a fastener 42 configured to couple the keychain 40 to another object, such as to a belt loop, backpack strap, briefcase handle, vehicle key ring, or the like. In an embodiment, the fastener 42 may be a carabiner although other quick connect fasteners would work. Further, the keychain 40 may include a dock member 44 opposite the fastener 42 that defines a docking port having a configuration complementary a configuration of the mounting portion 20 of the finger support apparatus 10. Accordingly, a user can keep the mounting portion 20 of the finger support apparatus 10 connected to the keychain 40 for storage, transport, and the like and, then when needed, release it from the dock member 44 of the keychain 40 and plug it into the smart phone case. Keeping the finger support apparatus 10 joined to the keychain 40 is primarily to prevent theft, misplacement, or damage.

In still another aspect and as shown in FIGS. 6, 7, and 8, a small and low-capacity battery 50 (also referred to as an auxiliary battery) may be positioned in an interior area of the body portion 30 (FIG. 8) and mat be electrically connected to the inlet plug 22 of the mounting portion 20 of the finger support apparatus 10. More particularly, the auxiliary battery 50 may be electrically connected to the inlet plug 22 with traditional wires and electronics or may transmit an electrical charge using inductive charging technology. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. This is advantageous in that the charge may be communicated without a direct contact or wire connection.

Accordingly, electrical power from the auxiliary battery 50 may be transferred to the battery power source of the computing device 12 via the inlet plug 22 when the finger support apparatus 10 is mounted thereto as explained above. In one embodiment, the finger support apparatus 10 may include an intermediate charging cap 60 having electrical storage media therein and a charging port 62 by which the charging cap 60 may electrically connect to a charging cable 16 to be charged or recharged. In an embodiment, the electrical storage media may be a low-capacity battery 61 (also referred to as an auxiliary battery 61) capable of receiving electrical current via the charging cable 16 that may be plugged into a wall outlet at one end and to the auxiliary battery 61 at the other end. Then, the charging cap 60 may be electrically connected to the finger support apparatus 10, whereby to provide the charge of electricity to the auxiliary battery 50 and, indirectly, to the battery of the mobile computing device 12. This is advantageous in that the charging cap 60 may kept plugged into a home's electricity and stay charged until it is needed while the finger support apparatus 10 remains mounted to the mobile computing device 12. As shown, the charging cap 60 may include a connection port 66 configured to receive the input plug 22 of the mounting portion 20 of the finger support apparatus 10 and be electrically configured to transfer stored electrical power.

In use, the finger support apparatus 10 may at first be carried on the keychain 40 as described above, e.g., for transport or storage. But, when desired, the finger support apparatus 10 may be released from the keychain 40 and the mounting portion 20 may be inserted into a port 14 of a mobile computing device 12, e.g., a smart phone. The body portion 30 may be rotated relative to the mounting portion 20 as may be most comfortable and desirable to the user. Accordingly, the pinky finger of the user may be positioned on and supported atop the top face of the body portion 30 as the mobile device is held by a single hand of the user. If the main battery power source of the mobile computing device 12 is below a predetermined level, electrical current stored within the auxiliary battery 50 may be transferred to (and recharge) the main power source.
